4 Claims. (Cl. 252-116) This invention relates to a cleanser forglassware, china, porcelainware, tile, painted or varnished surfaces,woodwork, metalware, silver,

, jewelry, clothes and the like.

Specifically this invention relates to a cleanser .containing titaniumdioxide in water-dispersible form.

Titanium dioxide powders have heretofore been used in paints, lacquers,leather finishes, printing inks, shoe cleaners, paper, rubber, plasticsand In all of such materials, the titanium dioxide functioned as apigment and, as such, it

had'to remain in or on the pigmented material.

- The present invention now provides a soap or cleanser containinga-water-dispersible titanium dioxide which is removed from the surfacebeing cleaned. In the cleanser of the present invention the titaniumdioxide is admixed with other ingredients such as ground silica or otherscouring grit material and powdered soap or other de- The titaniumdioxide present in this cleanser functions to stabilize soap suds orfoam. to absorb oil and grease, to neutralize the effect of alkalies onthe skin, and to mask and lubricate the scouring grit particles whileholding these particles on the surface being cleaned.

Suitable water-.dispersible titanium dioxide powders for the cleansersof this invention are marketed that contain a minimum of 97% TiOz andare preferably surface-treated with wetting agents to increase thedispersibility of the TiOz in water. The powders are ground to afineness such that 99.7% will pass through a 300-mesh screen. Thepowders have a high specific gravity range of 3.88 to 4.20, a very highwater absorption capacity of from 33 to 50 lbs. of water per. 100 lbs.of powder, and a high oil absorption capacity of from 1'7 to 21 lbs.ofoil per 100 lbs. of powder.

Any suitable water-dispersing agent, such as the dioctyl ester of sodiumsulfosuccinic acid, monobutyl diphenyl sodium monosulfonate, fattyalcohol sulfates or the like can be used to surfacetreat titaniumdioxide for increasing its dispersibility in water.

In the cleansers of this invention the titanium dioxide powder is sovery fine that it can coat and mask the scouring grit particles, causingthe grits toroll on each other, thereby eliminating scratching.

rinsed with warm water. The glassware had a brilliant luster and wasfree from grease and dirt.

4 From the above examples and explanations it should be understood thatthe invention provides a cleanser which. can be marketed -in drypowoxide. The titanium dioxide is not used as a pigment but is removedfrom the cleansed material by'rlnsingor the like.

It will, of; course, be understood that various details of the productcan be varied through a wid'e range-without departing from theprinciples of this invention and it is, therefore, not the purpose tolimit the patent granted hereon otherwise than necessitated Jay thescope of the appended claims.
